Toyota Reveals Liquid Hydrogen-powered Concept Hypecar Ahead of Le Mans 24 Hours Race

Toyota has unveiled the GR LH2 Racing Concept at the Circuit de la Sarthe ahead of the 2025 Le Mans 24 Hours. This hydrogen-powered prototype is based on the GR010 Hybrid Hypercar from the World Endurance Championship (WEC) and was developed by Toyota Gazoo Racing Europe in Germany. The hydrogen combustion powertrain was engineered at Toyota’s Higashi-Fuji Technical Centre in Japan, though full technical specifications have not been disclosed yet.

Toyota has built a strong foundation in hydrogen racing since 2021 through Japan’s Super Taikyu series. It began by using modified Corolla race cars and made a significant leap in 2023 with the second-generation GR Corolla H2. This model marked Toyota’s shift from gaseous to liquid hydrogen.

Toyota first hinted at its Le Mans hydrogen racing ambitions in 2023 with the GR H2 Racing Concept show car. Since then, the company has stated that any competitive entry would depend on official motorsport regulations. With new rules in place for hydrogen use, Toyota is now better positioned to push forward its hydrogen-powered Le Mans plans.

The FIA World Motor Sport Council approved liquid hydrogen safety regulations and these guidelines include strict protocols for storage systems, vehicle integration, and pitlane refuelling. Safety measures such as pressure-tested compartments and hydrogen leak detection systems are now mandatory, opening the door for manufacturers like Toyota to race within a regulated hydrogen motorsport framework.

With the Toyota GR LH2 Racing Concept, the brand continues to lead in hydrogen fuel innovation within endurance racing. Although a race debut has yet to be confirmed, recent FIA approvals and Toyota’s ongoing R&D suggest hydrogen-powered entries could soon be part of the Le Mans and WEC grid. This represents a major step toward sustainable racing using liquid hydrogen combustion technology.
